Abstract

As for the AC-DC hybrid micro-grid in this paper

a kind of coordination control strategy for controlling DC bus voltage and AC system voltage as well as frequency stability is proposed. The photovoltaic system and the wind power system of DC part are controlled by MPPT. The hybrid control of the battery and super capacitor takes over the remaining power to control the DC bus. The AC part has improved the original sag control. The control unit of the diesel synchronous generator improves the speed regulating systemand exciting system with addition of sag control and performs sag control for the DC/AC inverter so to participate jointly frequency and voltage regulation of the system. The effectiveness of the control algorithm inthis paper is verified by the PSCAD simulation platform.
